Hello,
Patch in the bottom extends truncation insn patterns.
Bootstrapped.
AVX-512* tests on top of patch-set all pass
under simulator.
Is it ok for trunk?
gcc/
* config/i386/sse.md
(define_insn
sse2_avx_avx512f_fix_notruncsf2simodelowermodemask_name):
Add masking.
(define_insn fix_truncv8sfv8si2mask_name): Ditto.
(define_insn fix_truncv4sfv4si2mask_name): Ditto.

Thanks, K
